Abstract

Strongly enhanced second-harmonic generation is observed from a two-dimensional square lattice GaAs/AlGaAs photonic crystal waveguide when the fundamental beam, the second-harmonic beam, or both beams resonantly couple to a leaky eigenmode. P -polarized second-harmonic spectra are obtained for s -polarized, 150-fs pump pulses that are tuned from 5000 to 5600 cm-1 and directed along the Γ–X direction of the crystal for various angles of incidence. Compared with off-resonant conditions, enhancements of >1200× in the second-harmonic conversion are observed for resonant coupling of both the fundamental and the second-harmonic fields to leaky eigenmodes. The angular and spectral positions of the peaks are in good agreement with simulations.
